The purpose of this study is to explore the acceptability and feasibility of weighted blankets in total knee replacement (TKR) patients.

Inclusion Criteria:

1. Adults aged 18 years and older
2. Adults undergoing elective total knee arthroplasty at NYU Langone Orthopedic Hospital.
3. Adults who are scheduled to receive spinal anesthesia.
4. Subjects with a planned same day discharge to home from the PACU

Exclusion Criteria:

1. cognitive disability that would interfere with their ability to complete the study's pre and post assessments (e.g. dementia, non-verbal)
2. subject disclosed history of pre-existing anxiety disorder, claustrophobia, epilepsy, respiratory conditions (e.g. obstructive sleep apnea (OSA), asthma), skin conditions (e.g. pressure injury), which are contradictions for weighted blanket.
